Removes InventoryView's broken duplicate Global Catalogue tab, which
misused createproductlocation with catalogue ids that never match real
product ids (imports silently failed to land) and showed fabricated
Math.random() pricing/ratings. "Import Product" now routes to the
already-correct CatalogueBrowser instead.
Also fixes catalogueApi's product_count field mismatch (brand chip
counts were always blank), a pagination bug that capped the catalogue
at 100 of ~237 products with no way to see the rest, and replaces
ImportProductModal's free-text category id input with a real dropdown
scoped to the tenant's own categories, filtering subcategories to match.
